The compounds and compositions are useful as catalysts in IN the polymerisation of olefins. In particular, the compounds and compositions are useful catalysts in the preparation of low molecular 0 weight polyethylene (e.g. polyethylene wax) and copolymers formed from the polymerisation of ethylene and other ct-olefms. ei O [Continued on next page] WO 2017/194943 Al 111 0 SD, SE, SG, SK, SL, SM, ST, SV, SY, TH, TJ, TM, TN, TR, TT, TZ, UA, UG, US, UZ, VC, VN, ZA, ZM, ZW.
